The thing I don't understand is how this could be a planned defense move if the other inmate was told by KC to flush the letters? Do you believe she was in on it as well?
I don't think it was staged by the defense. I do think that Casey, miss budding lawyer, took it upon herself to try and help her own defense with these letters. In them, she mentions something about Baez wanting her teach him stuff. Maybe she thought she was so smart, she could "fabricate" these letters, and they would help her get out of prison. Or if they weren't discovered, no biggie, it was all just fun and games anyway. I think her excitement was in the possibility of them actually being discovered, but I'm not sure if she really thought they would be. Does that make sense?
I think after the letters were discovered, and Baez realized what she had done right under his dang nose, the defense then had to think of a way to deal with these letters and their contents. It's obvious she had no input from anyone but her own observations and what Baez let her see on the internet. I'm telling you, had the defense sat down with her to write these letters, there would be much more anguish over losing her child, more intensive and better versed anger against her family, and much less mundane crap that just makes the reader want to vomit. In other words, she would be believable, not laughable.
No lawyer worth their salt is going to condone their client writing something that makes him or her sound like a whiny, immature, uncaring, stage five clinger with some kind of serious personality disorder the way Casey comes across. This is no way humanizes her, makes her seem any less guilty, or gives the impression that Caylee meant anything to her. And they already bypassed the insanity plea, can't go back to that at the last minute or it only makes them look all the more desperate.
IMO, this was Casey trying to help herself and doing a piss poor job of it. And now Baez and Mason have to try and clean up this latest mess. Good luck with that guys. Regretting taking this case yet, Mason? Is it still fun for ya?
